Acetylene-gas generator



Sept 18, 1928. 1,684,979 A. VALENTOUR ACETYLENE GAS GENERATOR Filed May 10, 1927 INVEN TOR kyz'n/rau/tf ATTORNEY outlet port 30 "and'with the valveinthe posipressure of the air within the holder 23 is such as to prevent the water rising into the pipe Q lso that the carbide remains dry "until the valve 33 is opened. Thereupon the water rises in the pipe 24 and passes through-the perforations in said pipe to the carbide C.

It is intended that only'the lower part of thecarbiderecep shall be Provided with hide so that the gas generated may either pass up through the mass of carbide or out through this screen and the side wall of the holder 23 and then back through the screen and the within the through the neck 18, the filterand pipe l l'and perforations oft-he pipe 24 into the space bell 19. From here it may flow up through the valve into the main 36. When it is desired to shut offthe generation of carhide the valve is first turned to the position shown inFigure 5 This stops further flow from the interior of the bell 19 through the pipe'14 but the carbide, being. still wet, will continueto generate a certainanaount of gas.

If this gas is in excessof that which can be held in the bell 19 it will flow downward under the edges of the bell 19 and up within theshell 22, the bypass 31 permitting escape to the ma'in'36. j Att-he same timethe pressure due to the gas generated within the bell 19 will drive the water out of thebell at least to a point below the lower perforations of the' pipe 24 and even entirelyout'of the bell in case sufiicient gas isgenerated. When the generation of the gas entirely ceases the valve may, ifdesired, again be turned to the position shown in Figure 3. In order to provide for changes in the water level the usualvent 37 is arranged on'top of the cover ll.

There has thusbeenprovided a simple and jflicient device of the kind described and for thepurpose specified. 1

It is not, therefore, desired to confine' the invention to the exact form herein shown and described, butit is desired to include all suchas properlyconie within the see c claimed, c0 1 aving thusd'escribed the invention, what is clalmedas new,is: 1
